Big crystals.
An example of the element Tellurium

Big crystals.
I was about to bid too much for some small tellurium crystals on eBay. Fortunately Max came to my rescue, saying he had plenty and it wasn't really very expensive. So now I have a nice big chunk and it didn't cost me anything.

I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
